Description

Technical Field

[0001] The utility model relates to a flaw detection tooling, in particular to a brake disc flaw detection tooling with adjustable stroke. Background Art

[0002] In the field of automobile manufacturing, as a key braking component, the quality and safety of the brake disc are directly related to the driving safety of the vehicle. Therefore, strict flaw detection of the brake disc is an essential part of the production process. Most traditional flaw detection toolings adopt the method of squeezing and fixing with clamping plates on both sides. Although this method is simple, there are many deficiencies in actual operation. First, due to uneven stress when the clamping plates on both sides clamp and fix, deflection is likely to occur, resulting in ineffective fixation of the brake disc in the fixture and a risk of detachment. This not only damages the equipment but also may endanger the safety of the operator. Second, the detection efficiency of the traditional tooling is low. Only one brake disc can be detected at a time, and the time for the detection table to enter and exit the flaw detection equipment accounts for a relatively large proportion of the total detection time. This will seriously affect the production efficiency when facing a large number of samples to be detected.

[0003] With the rapid development of the automobile industry, the requirements for the production efficiency and quality of brake discs are getting higher and higher. Therefore, there is an urgent need for a new type of flaw detection tooling that can not only improve the efficiency of flaw detection but also ensure the fixing stability of the samples to be detected. At the same time, the simplicity of operation and the protection of equipment and finished products should also be considered. Although there are some improved flaw detection toolings on the market, they often have problems such as complex structure, high cost, or limited application range, and are difficult to meet the needs of modern production lines.

[0004] Aiming at the deficiencies of the existing technology, the utility model proposes a brake disc flaw detection tooling with adjustable stroke, aiming to solve the problems of unstable fixation and low efficiency of the traditional tooling through innovative design, and achieve high-efficiency and high-stability flaw detection to meet the strict requirements of modern automobile manufacturing for brake disc quality control.

[0008] Furthermore, a rubber strip with a thickness not exceeding the straight groove is embedded in the straight groove.

[0009] Furthermore, one or more rubber strips are placed or adhered on the slide rail between a pair of the clamping frames.

[0010] Furthermore, the position of the brake disc in the vertical direction is adjusted by adjusting the number of rubber strips.

[0011] Furthermore, the width of the straight groove is equal to or slightly greater than the thickness of the rim of the brake disc.

[0012] Furthermore, a reinforcing rib is provided between the flat plate and a side of the vertical plate close to the free end of the flat plate.

[0013] Furthermore, in a pair of the clamping frames, one of the clamping frames is close to one end of one of the slide rails and is fixed, and the other clamping frame can be moved along the length direction of the slide rail and then fixed to accommodate brake discs of different diameters.

[0014] Furthermore, the nut of the bolt is a butterfly nut.

[0015] Furthermore, a tension spring is provided in the T-shaped notch of the slide rail, and two ends of the tension spring are respectively connected to the flat plates of a pair of the clamping frames.

[0023] 6. High structural strength and good durability: Reinforcing ribs are provided on one side of the vertical plate close to the free end of the flat plate, enhancing the structural strength of the clamping bracket, enabling it to withstand greater clamping force and improving the durability of the tooling.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0029] The following specific embodiments illustrate the implementation manners of the present utility model. Those who are familiar with this technology can easily understand the other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0030] As Figure 1-2 shown, a brake disc flaw detection tooling with adjustable stroke includes a bottom plate 1. There are 6 rows and 6 columns of screw holes 11 arranged linearly on the bottom plate 1. Two T-shaped groove-opening rails 2, one horizontal and one vertical, are fixedly arranged on the bottom plate 1 through the screw holes 11 and the screws screwed therewith. A pair of clamping frames 3 are arranged above each rail 2. Each clamping frame 3 includes a flat plate 31, and a vertical plate 32 is fixedly connected to one end close to the flat plate 31. Long strip holes 33 corresponding to the opening width of the T-shaped groove openings are opened on the flat plate 31. Two bolts 4 fixedly connect the flat plate 31 and the rail 2 adjustably through the long strip holes 33. A vertical straight groove 34 is opened on one side of the free end of the vertical plate 32 away from the flat plate 31. The two sides of the rim of the brake disc 100 enter the two opposite straight grooves 34 of a pair of the clamping frames 3 and are clamped in the horizontal direction, and the bottom of the rim of the brake disc 100 is supported by the rail 2 in the vertical direction.

[0031] In this embodiment, a rubber strip 5 with a thickness not exceeding its depth is embedded in the straight groove 34, and one or more rubber strips 5 are placed or adhered on the slide rail 2 between a pair of the clamping brackets 3. The embedding of the rubber strip 5 increases the friction force between the inner wall of the straight groove 34 and the rim of the brake disc, thereby improving the clamping stability of the brake disc in the horizontal direction and preventing sliding or displacement during the flaw detection process. The material of the rubber strip 5 is relatively soft, which can avoid direct contact and potential scratches or damages caused by the metal straight groove 34 to the rim of the brake disc, protecting the surface integrity of the brake disc, which is particularly important for brake discs that have completed painting or other surface treatments. The rubber strip 5 has a certain elasticity, which can absorb vibrations and impacts that may occur during the flaw detection process, reducing damage to the flaw detection equipment and the brake disc, and also reducing noise. When clamping and releasing the brake disc, the softness of the rubber strip 5 can provide a better grip, reducing the discomfort that the operator may feel due to direct contact with hard metal. As a consumable part, the rubber strip 5 is designed to allow for quick replacement and maintenance without a complex disassembly process, thereby reducing the maintenance cost during long-term operation. By reducing direct contact and friction between metals, the rubber strip 5 helps to extend the service life of the straight groove 34 and the slide rail 2, reducing the accuracy degradation and maintenance requirements caused by wear. The embedding of the rubber strip 5 provides a certain elastic space, enabling the tooling to adapt to brake discs of different thicknesses or sizes, enhancing the versatility and flexibility of the tooling.

[0032] Adjust the position of the brake disc 100 in the vertical direction by adjusting the number of the rubber strips 5. By increasing or decreasing the number of the rubber strips 5, the height of the brake disc 100 relative to the flaw detection equipment can be accurately adjusted to ensure the accuracy and effectiveness of the flaw detection operation. This design provides a simple and flexible way to adapt to brake discs of different thicknesses without complex mechanical adjustments or component replacements, and the operator can quickly adjust the position as needed.

[0033] In this embodiment, the width of the straight groove 34 is equal to the rim thickness of the brake disc 100. The matching of the width of the straight groove 34 with the rim thickness of the brake disc 100 can ensure that the brake disc is firmly clamped in the horizontal direction, preventing sliding or displacement during the flaw detection process.

[0034] In another preferred embodiment, the width of the straight groove 34 is slightly larger than the rim thickness of the brake disc 100. The width of the straight groove 34 being slightly larger than the rim thickness of the brake disc 100 can provide a certain amount of movement space for the brake disc, avoiding damage caused by over-tight clamping, and also adapting to brake discs of different thicknesses. This improves the versatility and flexibility of the tooling.

[0035] In this embodiment, a reinforcing rib 35 is provided between one side of the vertical plate 32 close to the free end of the flat plate 31 and the flat plate 31. The provision of the reinforcing rib 35 can significantly improve the overall structural strength of the clamping bracket 3, preventing deformation or breakage caused by excessive clamping force applied during the clamping process. By adding the reinforcing rib 35, the pressure applied to the vertical plate 32 can be effectively dispersed, enhancing the stability of the clamping bracket 3 during use and ensuring the fixing effect of the brake disc 100 during the flaw detection process.

[0036] In this embodiment, the bottom plate 1 is fixedly connected to the rotating detection platform of the flaw detector. Since the bottom plate 1 is fixedly connected to the rotating detection platform, the brake disc 100 can be quickly moved from one detection position to another, thereby improving the working efficiency of the flaw detection.

[0037] In another preferred embodiment, among a pair of the clamping brackets 3, one of the clamping brackets 3 is fixed near one end of one of the slide rails 2, and the other clamping bracket 3 can be moved along the length direction of the slide rail 2 and then fixed to adapt to brake discs 100 of different diameters.

[0038] In another preferred embodiment, the nut of the bolt 4 is a wing nut. A wing nut, also known as a wing-shaped nut, can quickly adjust the stroke. It allows single-handed operation, which means that the operator can quickly adjust the bolt 4 with one hand while holding the brake disc 100 with the other hand, improving the working efficiency. It reduces the dependence on professional tools.

[0039] In another preferred embodiment, a tension spring is provided in the T-shaped notch of the slide rail 2, and the two ends of the tension spring are respectively connected to the flat plates 31 of a pair of the clamping brackets 3. The tension spring can provide equal pulling force for the clamping brackets 3, helping the clamping brackets 3 to automatically center, ensuring the centering positioning of the brake disc 100 during the clamping process. The use of the tension spring can reduce the need for manually adjusting the position of the clamping brackets 3 because the elasticity of the tension spring can automatically adjust the position of the clamping brackets 3 to adapt to brake discs 100 of different sizes. The use of the tension spring provides a gentle clamping method, which can reduce the impact and pressure on the brake disc 100 and protect its surface from damage. The design of the tension spring allows for the quick release of the clamping brackets 3, facilitating the quick loading and unloading of the brake disc 100 and improving the working efficiency.

[0040] Although the present invention has been described in detail above with general descriptions and specific embodiments, based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
